If mArc BC is 105°, what is mArc CD? (3 points)

1 answer:

8 0

Well, its a given more or less when referred to the measure of an Arc, it's usually meant the CENTRAL ANGLE made by that arc in this case, 148 is the CENTRAL ANGLE, so if BCD is 148 and BC is 105, then CD is the rest of the 148. 148 for the central angle, if we use up 105 for BC, how much is left over for CD?

If y varies inversely as x2 and y = 3 when x = 2, find the equation that connects x and y.

Bond [772]

<h3>Answer: y = 12/(x^2)</h3>

============================================================

Explanation:

"y varies inversely as x^2" means y = k/(x^2) for some constant k.

Plug in (x,y) = (2,3) and solve for k

y = k/(x^2)

3 = k/(2^2)

3 = k/4

3*4 = k

12 = k

k = 12

The original equation updates to y = 12/(x^2)

As a check, plugging in x = 2 should lead to y = 3

y = 12/(x^2)

y = 12/(2^2)

y = 12/4

y = 3 ... we get the proper y value, so the answer is confirmed.

Find an equation of variation in which y varies inversely as x and y = 5 and x = 17. then find the value of y when x=10

Brilliant_brown [7]

Y=5 -- x =17
so y= 5*10/17= 50/17 when x = 10
